With the birth of the portable crane in the Spring Rain in 2002, the market for portable cranes has continued to expand, and the market for cranes has developed very rapidly. Among them, the wire rope is an indispensable part of the small lifting machine. The quality of the wire rope has a significant impact on the lifting efficiency and the lifting safety. Let me tell you about the correct selection of wire rope:
At present, most manufacturers choose 5mm steel wire rope, and some individual manufacturers also use 4mm or 6mm steel wire rope. Many consumers think that the rope is thinner and require a thicker one. This is wrong. The thickness of the wire rope is important, but quality is the first priority. The 5mm wire rope used by general manufacturers, if it meets the national standard, has a tensile force. It can reach more than 1800 kg, so there is no need to worry about weight bearing. However, the diameter of the wire rope has an impact on the hoisting machine. The motor speed is a fixed speed. The thicker wire rope and the larger sheave will cause the speed to be fast. The fast speed will reduce the lifting weight, so the diameter of the wire rope must be reduced. Steel wire rope with high strength, good elasticity, light weight and good flexibility is the best choice.
